The Stats 12 ft. Rectangle Trampoline and Enclosure is made with a patented Stay-Put enclosure design with buttonholes. This feature attaches the netting to the jumping surface, eliminating gaps. Made of thick, UV resistant materials, the tightly woven enclosure netting helps prevent kids from climbing the net. The rectangular shape increases bounce with a total of 76 thick, rust resistant springs. Reinforced T-Sockets at each leg and frame joint stabilize the upper enclosure to trampoline frame, preventing structural twisting. Made with galvanized heavy gauged steel frame for rust resistance and longevity. Meets all ASTM safety requirements.
